[jira] [Commented] (CXF-6769) Underscores in values of FIQL search expressions are incorrectly escaped

    [ https://issues.apache.org/jira/browse/CXF-6769?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15231929#comment-15231929 ] 

Torsten Römer commented on CXF-6769:
------------------------------------

I've just tried this and while this would solve our problem, we unfortunately can't use in our setup.

We are running in WildFly 8/10 which includes Apache CXF, but uses RESTEasy instead of CXF's RS implementation. So we basically just include cxf-rt-rs-extension-search in our WAR deployment and create our "own" instance of FiqlParser (all we want to do is to convert an FIQL expression to an SQL query):

{code}
        final FiqlParser<SearchBean> fiqlParser = new FiqlParser<>(SearchBean.class);
        final SearchCondition<SearchBean> searchCondition = fiqlParser.parse(search);
        final SQLPrinterVisitor<SearchBean> visitor = new SQLPrinterVisitor<SearchBean>(table);
        searchCondition.accept(visitor);
        final String sql = visitor.getQuery();
{code}

And like that we are not able to set the property.

Any suggestion?

> We are basically "just" using FIQLParser and SQLPrinterVisitor like this:
> final FiqlParser<SearchBean> fiqlParser = new FiqlParser<>(SearchBean.class);
> final SearchCondition<SearchBean> searchCondition = fiqlParser.parse(search);
> final SQLPrinterVisitor<SearchBean> visitor = new SQLPrinterVisitor<SearchBean>(table);
>         searchCondition.accept(visitor);
> final String sql = visitor.getQuery();
> A search expression like this:
> text==VAL_UE
> yields an SQL query like this:
> SELECT * FROM some_table WHERE text = 'VAL[backslash]_UE'
> (Note [backslash] is supposed to mean a literal "\" which is swallowed here)
> If the table contains a row with text "VAL_UE", the query returns no results because the underscore in the value was preceded with a backslash.
